Question

Which of the following is true about main and secondary memory?

Answer 1

Answer:

Main memory is short term memory used by the CPU in processing commands, secondary memory is more permanent and used for storage.

Explanation:

Hey there so just a quick explanation here.

Main memory is not used for storage and secondary memory is not lost when the device's power is turned off.

That leaves you to two possibilities:

• Main memory is more permanent and used for storage, secondary memory is short term memory is used by the CPU in processing commands.
• Main memory is short term memory used by the CPU in processing commands, secondary memory is more permanent and used for storage.

The bolded bullet point is the correct answer because, main memory is what's know as RAM on your computer. It could either be 4GB, 8GB or maybe even 16GB of RAM. But this is known as Random Access Memory, this is data stored no on the hard drive but on the processor, only momentarily and used when the CPU needs it.

Secondary memory is your Hard Drive, typically 256GB, 500GB, or 1TB which is 1000GB's. But this data is stored on the Hard Drive or Solid State Drive (SSD) and it stays there even when the computer is shot off.

Kind of like our phones, we take pictures on a Friday night dancing with our friends, but our phone dies. Saturday morning we wake up and haha! We get to see all the funny pictures we took that night, so even though it shuts off, our data is saved and secured.

Hope this helps and Good luck !!

Happy Coding :)
